I'm partial to the ones that smoothly sweep forward from the front to the side, maybe because I'm familiar with the RAD method. To my eye the ones that snap from the side have a jerky quality to them.

They also have a decidedly downward accent. If a dancer performs Cecchetti fouettés, she's back up on pointe by the time her leg reaches the side, so the turns have an upward accent that feels less plunky.
